Kenmore Elite 722 Dishwasher Code IE / OE (722-prefix): Inlet and Drain Trouble

Warranty: 30-day workmanship

What IE / OE (722-prefix) means

Among Kenmore Elite dishwashers with the 722 prefix, an LG-built platform, IE is a water inlet problem and OE is a drainage problem. IE means water is not reaching the tub as expected, while OE usually means the drain is blocked at the air gap, disposal or filters. The owner sees IE or OE in the display, and the cycle stops or stays in the same step. The maker is inferred from the part numbering, not named in the paperwork.

Common causes of IE / OE (722-prefix)

Water supply valve and inlet hose for IE
Inlet screen and fill valve
Air gap, disposal connection and drain hose for OE
Filters clogged with debris

✓ One safe check you can try

1. For IE, make sure the water supply valve under the sink is open and the inlet hose is not kinked. 2. For OE, check the drain hose for kinks and clear the air gap or disposal. 3. Pull out and clean the filters. 4. Check that the dishwasher is level. 5. Run a short cycle.

! Why to stop there

IE and OE both depend on household plumbing as much as the dishwasher, so the cause may sit outside the machine.
We check the supply and drain connections before we test the valve or pump.
You approve a written price first and receive a 30-day warranty on the work.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

IE / OE (722-prefix)IE / OE (722-prefix) questions

What is the difference between IE and OE?

IE is an inlet problem, meaning water is not coming in as expected. OE is a drainage problem, meaning water is not leaving the tub. Both show on 722-series Kenmore Elite dishwashers.

Can the disposal cause OE?

Yes. If a new disposal still has its knockout plug, or the air gap is clogged, the dishwasher cannot drain and will report OE until the path is open.

Is my dishwasher an LG product?

Kenmore Elite 722-series units look LG-built from their part numbering, but that is an inference, and we do not claim any link to LG. We still run the inlet and drain tests the same way.
